© 2017 Taylor & Francis Group, London. Steel tubular T-joints are one of the simplest and widely used connections used in connecting structural members. Stress concentration usually exists at the vicinity of the joint. In this paper, variation of the maximum Stress Concentration Factor (SCF) with non-dimensional geometric parameters β, τ, γ and α in concrete-filled steel tubular (CFST) T-joints under axial tension has been investigated. Graphs showing variation of the maximum SCF, in CFST T-joints, with non-dimensional geometric parameters have been developed and compared with those for non-filled empty T-joints. The graphs showed that parameter has the most influence. The graphs also showed that the variation pattern in the CFST is different to that in the empty T-joints except the variation of parameter.
